COMPONENT PARTS

CVT CONTROL SYSTEM : Malfunction Indicator Lamp (MIL)

INFOID:0000000009019851

The malfunction indicator lamp (MIL) is located on the combination

meter.

The MIL will illuminate when the ignition switch is turned ON without

the engine running. This is a bulb check.

When the engine is started, the MIL should turn off. If the MIL

remains illuminated, the on board diagnostic system has detected an

engine system malfunction.

For details, refer to 

EC-24, "WARNING LAMPS/INDICATOR LAMPS

: Malfunction Indicator Lamp (MIL)"

STRUCTURE AND OPERATION

Mechanism

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt

(the steel plates are placed continuously and the belt is guided with the multilayer steel rings on both sides).

The groove width changes according to wrapping radius of steel belt and pulley from low status to overdrive

status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.

Steel belt

It is composed of multiple steel plates (A) and two steel rings (B)

stacked to a several number. The feature of this steel belt transmits

power with compression of the steel plate in contrast with transmis-

sion of power in pulling with a rubber belt. Friction force is required

with the pulley slope to transmit power from the steel plate. The force

is generated with the following mechanism:

Oil pressure applies to the secondary pulley to nip the plate. 

⇒The

plate is pushed and extended outward. 

⇒The steel ring shows with-

stands. 

⇒Pulling force is generated on the steel ring. ⇒The plate of

the primary pulley is nipped between the pulley. 

⇒Friction force is

generated between the steel belt and the pulley. 

Therefore, responsibilities are divided by the steel plate that trans-

mits the power with compression and the steel ring that maintains necessary friction force.   In this way, the

tension of the steel ring is distributed on the entire surface and stress variation is limited, resulting in good

durability. 

Pulley

The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope

(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-

sure chamber at the back of the movable sheave. 

Pulley gear shifting operation 

• Pulley gear shifting operation 

The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine

load (accelerator pedal opening), engine revolution and gear ratio (vehicle speed) change the operation

pressures of the primary pulley and the secondary pulley, and controls the pulley groove width.   Along with

change of the pulley groove width, the belt contact radius is changed. This allows continuous and stepless
